**** Visit: www.LockPickingVideos.net **** 6 double-spooled ASSA drivers, countermilled chambers and 5 serrated sidebar pins. Thanks Farmerfreak @ Keypicking for the lock. This took a LOT of practice to get it this fast and was an extreme challenge.. probably the hardest lock I've ever picked to date. This lock claimed the life of my Peterson Gem... RIP. I was going to disassemble this but putting it back together is an absolute nightmare without a key. www.keypicking.com
